I just got my big stuff 3 from LS1 speed and i have problem with it that when we install it every thing looks good but when we need to start the car there is no crank and cam signal so you will not see any sparck at all and it wont start we change the sensors and still the same thing , any one had this problem befor i take it out and send it back to them to cheack on it .

thanks
